Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. Public Information Logo and Guidelines. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

You can be creative with what they are sampling, but this label helps with misconceptions, such as that fossil fish have their own half lives, and not the carbon in them. It was easy to get caught up in the nomenclature, even though the things they describe should be familiar. Finally, correlation between different isotopic dating methods may be required to confirm the age of a sample.
